Thanks for give the link. So it's intend to be that.
I'm still confused with the KMSG_DUMP_KEXEC.
crash_kexec() kmsg_dump(KMSG_DUMP_KEXEC) kmsg_dump(KMSG_DUMP_PANIC)
Looks like it's equal to original logic, isn't it?
kmsg_dump(anything); crash_kexec()
So why intruduce KMSG_DUMP_KEXEC? why not just kmsg_dump before crash_kexec?
thoughts?
